@En entre@ www @mm JOHN EBEL, OF soMEnv-ILLE, NEW JERSEY, AssIGNon rro BOUND BROOK OIL-nnss BEARING COMPANY, or BOUNDBROOIQNEWJERSEY, A CORPORATION or NEW JERSEY.

To all whom it may concern Be it known thatl, JOHN EBEL, alcitizen of the United States, and a resident of Somerville, in the county of Somerset and State of New Jersey,` have invented certain new and useful Improvementsin Bearing-` Indicators, of which the following 1s a full,

clear, and exact description, whereby any one skilled inthe art may make and use the same. f n The invention relates to a" bearing indicator which serves both as an advertising medium, and as a useful indicatorfor insuring proper-assembly and use of the parts of a self lubricating bearing.` WhenV used merely for advertising purposes, it serves as an instructor, indicating the application of one part to' another, and illustrates the method of lubrication. Y It may beused `for minder of themethod of lubrication em-` any convenientV purpose such y as a paper weight, if put out'simply for advertising x purposes, and thus becomesja constant ireployed. Y v*The invention relates more` particularly to the providing of a metallic shell having formed or cut therein certainindicia which when the shell` is divided in halves `and placed end Vto end,'w ill clearly show an`imprinted word.` f Y i n 'selecting the inserted or imprinted word, only such letters are used as will, when the two halves of the bearing are together,

produce substantially` spirally arranged" lines, or grooves with transverse bar portions, which in effect will providellinesof-` lubrication vof graphite or other suitable `lubricant which will permit a rotating shaft` ftocarry the lubrication over every `portion `40 of the metal. Y n

rThe object of the invention is to provide in an article of manufacture, a device which may serve the dualpurpose of an advertising medium and an indicator for a selflubricating bearing having unusual and,

most eiiicient qualities.

Referring to the drawings:

Figure 1 illustrates the two halves of a single piecebearing shell out in sections with letters arranged therein in the form of lubricating grooves or chambers.

Fig. 2 is a plan view on enlarged scale with the two halves of the bearing in place and with the `lettering shown in dotted BEARING-INDICATUR.

outline to illustrate the arrangement of the grooves. y

Fig. 3 is a plan view similar to that of Fig` 2 illustrating the letters of a forward slanting type. Y

Figa is an end view of a single piece bearing.

Fig. 5 is an end view of a'split bearing.

' VIt is not newin the art to provide a selflubricating bearing or a bearing having grooves for the interior of its shell to hold a lubricant and therefore no `claim is made therein broadly to a groove.

`or grooves for the purpose` of inlaying a graphite material for lubrication, in a form to produce a useful mechanical structure and indicator for proper assembly. After Vits advertising value has been'utilized; it

may be employed as a unique form of paper-w`eight or for any purpose desired. When so used, it is a constant reminder of the method oflubrication employed, and serves to demonstrate the proper assembly of two halves of a bearing to get the eiiicient` lubrication required. A One of the first prerequisites of a selflubricating bearing, that is, such a bearing asis made of metal with grooves, having inserted therein a lubricating` material, is

. that the grooves be arranged in a substantially spiral form Vso that the rotating motion will carry the lubricant 'from the grooves across every" portion of the metal. It is also important thatl there be a maxi-` mum of lubricating material arranged in the'bearing commensurate with du'e regard to the strength of the shell.

VThe invention herein deiined relates to the utilization of grooves which when placed in a .specific arrangement read as a word. y

y Tha-t is, thegrooves, when combined, really form letters and the disposition and arrangement of the letters is such that there is a maximum body of `metallic strength and ample grooves for the lubricant.

As il ustrated in the drawing, the word lubricated is used merely for the purposes of illustration and it` should be observed that the various lettersare arranged Copies of this-patent may be Vobtained for transversely to the axis of the metal shell or in what might be termed a baclehand type of letter. Obviously, they might just as Well be formed in a forward slanting type so long as there is an angular disposition of the main portion of the letters which is transverse to the axis of the metal shell.

The letters, .as selected When the two sections of the metal shell shown in Fig. 1` are imposed one upon the other Will be trans verse to each other so that there is in eifect a series of spiral grooves reversi-ng direction at each 180C of a cylindrical bearing. In the accompanying drawings, the numeral l denotes a bearing shell ol1 compara-V tively tliin metal forming one-halt ot' a coinplete bearing and 2 indicates a similar tion. For the purposes ot' illustration, there is shown in the section l, the letters L U B R l and in the section 2, C A T E D. These letters are all arranged within the ex treme ends 3, d and 5 and 6 of the bearing sections l and 2 and as illustrated, are et a back-hand or slanting type of letter so that the upright lines of each letter :term

What is in substance a series of spiral grooves extending halt way about thebearing, While the cross-bars of the letters extend slightly transverse to the axis ot' the shell member and substantially at right angles to the main lines ofv the letters.

Tt Will be observed by reference to Fig. 2 of the drawings, due care is exercised in selecting letters which will give completelubrication; for instance, the letter D occupies a position transversely to the letter and the main lines of the letters are transverseto each other, While the loop of the D forms a groove which insures transmission ot the lubrication; similarly with the letters E and Uf T and ,R, C and 1. g

The metallic casing parts l and 2 are ordinarily formed of bright metal, such, for instance, as bronze and the grooves indieating the letters are filled With some lubricant or compound, preferably a compoundl of graphite. This shows clear letter markings of black against thebright metal shell. l/Vhen the two parts of the shell are in place, making a complete cylindrical structure, there is. no suspicion of a Word but When opened Vup longitudinally and placed end to end, there is immediately disclosed the advertising Word which may be of any letters will bear tliejrelatioi'i to each other indicated in Figs. 2 and 3. Wheiiso placed the proper lubricating ettect will be secured.

To draw morel particular attentionl to the device as an advertisingstructure, therespective ends of the shells may be grooved as at 7, 8, 9, 10, so that there will be a shewing of a black band of lubricant ateither end of the shell portions. This is also usci ful When the device is used mechanically.

.Ordinarily the devices are distributed in a complete cylindrical form and"` when opened, display` the advertising Werd, Whatever it may be. VOf course, the exterior of the shell may be embellished With suitable g inscriptions for advertising purposes.

The value of the device as an'advertising structure is apparent. It indicates vthe unique use `oit `letters tormingvvordsfinteriorly arranged as lubricating grooves in a mechanically useful and substantial bean Y ing. It also serves as an indicator jto in struct one in the proper assembly of .the

parts, and illustrates the spiral arrangement ot grooves for giving` complete and perfect lubrication.

What I claim as my invention and desire to .secureby LettersPatent is: f i

A bearing havingindicatorineans for denoting correct arrangement of the combined parts thereof, consisting of a .metallic shell`V having interior lubricating grooves, saidy grooves representingthe lett-ers et aVA coin`` plete Word and said structure providing "a complete bearing, said Word having a part of its letters in each half oitl` the bearing, and serving to indicate lthe proper assenti# bly of the halves of the bearing and contained grooves. y i JUHN EBEL.
